چکیده

Baryon stopping at the SPS and RHIC energies is calculated by introducing a new baryon junction mechanism into HIJING. The exchange of a baryon junction, according to Regge phenomenology, leads to a cosh[(y− yCM)/2] rapidity dependence and an 1/ 4 √ s energy dependence of the inclusive baryon cross section. This baryon junction dynamics also leads naturally to enhanced pT broadening in pA and AA together with enhanced mid-rapidity hyperon production.

Stopping and Baryon Transport in Heavy Ion Reactions

In this report I will give an experimental overview on nuclear stopping in hadron collisions, and relate observations to understanding of baryon transport. Baryon number transport is not only evidenced via net-proton distributions but also by the enhancement of strange baryons near mid-rapidity. Although the focus is on high-energy data obtained from pp and heavy ions from RHIC, relevant data f...

Baryon Number Transport via Gluonic Junctions

A novel non-perturbative gluon junction mechanism is introduced within the HIJING/B nuclear collision event generator to calculate baryon number transport and hyperon production in pA and AA collisions. This gluonic mechanism can account for the observed large mid-rapidity valence baryon yield in Pb + Pb at 160 AGeV and predicts high initial baryon densities at RHIC. However, the highly enhance...

Absence of anomalous stopping in heavy ion collisions

We show that the baryon stopping observed in heavy ion collisions both at CERN-SPS and at RHIC can be derived from the one observed in protonproton collisions. No increase in the size of the baryon junction component is required between small size (pp) and large size (AA) systems. LPT Orsay 02-43 May 2002 Unité Mixte de Recherche UMR n◦ 8627 CNRS A huge baryon stopping has been observed in cent...

A Transport Model for Heavy Ion Collisions at Rhic

To study heavy ion collisions at energies to be available from the Relativistic Heavy Ion Collider (RHIC), we have developed a transport model that includes both initial partonic and final hadronic interactions. Specifically, the parton cascade model ZPC, which uses as input the parton distribution from the HIJING model, is extended to include the quark-gluon to hadronic matter transition and a...

Strange Baryon Production From Nucleus-Nucleus Collisions at the AGS, SPS and RHIC

We will present a review of selected results on strange baryon production from nucleus-nucleus collisions at the AGS, SPS and RHIC. From the AGS and SPS heavy ion physics program several intriguing aspects: centrality dependence of strangeness production, anti-hyperon yield, hyperon production enhancement and baryon number transport will be highlighted. Our discussion on RHIC results will focus...
